OpenVPN Suggested Speed Improvement
Last updated by Shayne M on February 25, 2019 21:25
In some specific cases, adjusting some tunnel parameters may help increase the speed of the tunnel for you.
1) Open the VPN client.
2) Click on the Menu at the top left.
3) Select Settings
4) Select Advanced Config
In the OpenVPN Directive Field, please add the following one by one, clicking the Add button after entering in each line.
Once completed it will look like the below.
If this decreases your speed, we would suggest changing mssfix to 1350, then to 1450 - If this does not improve the speed then please remove these settings, trying TCP servers may also resolve the issue depending on your ISP/local configurations.
Locally installed firewalls may also cause a problem, Firewalls try to inspect the outbound/inbound traffic and because of the encryption it's unable too, this will slow down the VPN connection.
You may need to add "openvpn.exe" to the whitelist of your firewall program
Located in C:\Program Files\VPNSecure\lib\bin\windows\openvpn.exe
Or for Windows 10 - also add to Windows Defender exception list.
Adjusting the Cipher under Menu - Settings - Advanced can also check to see if other ports are working better with your ISP.
